I am preparing to convert my old Bose Companion 2 to ZigmaHornet Cabinet design to maximize its performance. I'll keep you update as soon as this thing is done. My only problem is time. The cabinet design is very good for both HT and audio. The cost is also cheap and easy to build.

Oo bro. Yung power amp chip ng Bose Companion 2 TDA7377. 2 X 30 @ 4 ohms. Meaning, max.power pala ng Bose speaker driver mga 15-20watts siguro. Kasi 5 watts RMS 4ohms siya. Tamang tama sa Zigmahornet. :)

Oo murang mura yan. Tapos Audio Nirvana Super 3 in cast frame. Pasok sa budget mo.

@monreq,
care to share the dimension? parang nasa 6" lang ang width ah. anong gagamitin mong material?

sir tony aka trod93 made a several of these and i must say these are one of the best sounding speakers I heard. the speakers will give some of the more expensive brands a run for their money

monreq, this is interesting project. Bose companion 2 is quite small speaker and small escursion movement. Hope this work fine! Keep us posted on the development! Goodluck!
This might be the best speakers for this project:

Thanks bro. Time and budget lang kailangan ko. Pero kating kating na talaga ako simulan. Regarding the compatibility of Bose Companion Fullrange to Zigmahornet cabinets. I would say it is experimental and risk on my side. However, I study the Fostex 103, the successful fullrange driver used in Zigmahornet (pls.click this link: https://www.madisound.com/store/product_info.php?cPath=45_241_309&products_id=8825 (https://www.madisound.com/store/product_info.php?cPath=45_241_309&products_id=8825), and found out that the only difference is the size and impedance. The actual size of Fostex 103 speaker driver is 3" and Bose Companion 2 is only 2.5". Bose is 4ohms 5 watts rms. The amp that is driving the companion is using TDA 7377 I.C chip which is 35watts maximum at 4ohms per channel. That means the Bose companion 2 has an estimated wattage of 5 - 15 watts @ 4ohms just like Fostex FE 103 fullrange driver.
Here are the exact pictures of Bose companion 2 fullrange speaker driver. It has midbass and clear sound reproduction even without box.

If ever the Bose Companion works perfectly fine with Zigmahornet cabinet. I will again disassemble my other Bose Companion 2 to make another one. Para pang center speaker ko. Ito kasing 1st experiment ko will be for surround. Since powered naman ang Bose Companion 2 and maganda naman ang amp niya, i think it will work out fine using only DTS/DD decoder from cheap DVD players if ever I want to use it for HT.
Now, if Bose Companion 2 will be a failiure. I still have lots of options on fullrange drivers. I can buy Audio Nirvana Super 3 in Cast frame or Fostex FE103 in this case, which will not be so extravagant to buy because of its size and weight.
I hope to finish this before this month end or else it will sing next month. I also hope it will be successful. Para di na ako bibili pa ng fullrange speakers.

As a suggestion, you can also get the specs of the actual 4" driver used by the original designer of the ZigmaHornet and have Anthony custom make it for you thru his supplier abroad.
If many of you would like to try this DIY speaker, having someone to supply the drivers would make the project more feasible as you only have to do the enclosure ;)
On the other hand, pwede rin cguro eto i-explore ni brader anthony to produce (driver & enclosure) for those who may not be inclined to DIY.

May nagawa na ata si anthony na 4'ers.

I like your suggestions Mr. Macdon and Nelson. But since this is just an experiment and already talked to my carpenter..his asking price for the cabinets in mahogany varnish finish is only P2K over all. Siguro, pag successful iyong experiment saka ko patira kay Anthony final finishing ng mga speaker cabinets ko, if budget permits. I am the one supervising para sigurado wala mali. Besides, the carpenter knows his craft. Siya din kasi tumira ng Audio NIrvana Super 8 floorstander ko.:)

Definitely sir ;) Iba talaga pag either ikaw ang gumagawa or sa harap nyo ginagawa - thats actually half the fun of the project! ;D
I was just trying to entice brader Anthony to possibly explore these types of speakers at malay natin baka isama nya sa regular production ng A-Audio.
The reviews naman sa net is enough warrant to atleast try and explore. Inexpensive, slim footprint and good sounds - perfect sa ating mga pinoys ;D
I am wishing for your success in this project sir Monreq - and hope you could give us feedback in the near future ;)
-
oo nga bro sana gumawa ng ganito si Anthony...puwedeng pang audio at HT at mas mura pa production cost. Pag bitin sa LF, subz lang katapat. Sabi din sa review madali daw i match sa subz ang zigmahornet cabinet design. :)

Hi
I used Sony 4" fullrange drivers for this Zigmahornet. Sounds good and impressive bass for its size. In fact, I made a complete HT setup on this. If you have the right drivers, this can be a great diy project. I've done 3 variants already and they all sound awesome.

My 6.1 HT setup.

IMO, the supposedly center channel is even better for audio compared to the fs.
I'm back to audio and all of these have been sold except for 1 pair for my personal use.
A week ago, one of the buyers called me and asked if I can modify it and make it sound even better. I'm now working on it. I added a horn tweeter and they now have 3D imaging. I will post pic when I'm done.
This one will look really different. Radical ito! Watch out for it.
If you have questions on the design just let me know. I will gladly answer your queries.

Naku sir - be careful of what you wish for ;D
I just heard from Anthony na tapos na daw yung woodworks - ikakabit nalang daw nya yung 4" coax nya kaso wala daw syang time at the moment.
I did recommend him to possibly try it out with a 4" fullrange rather than a 4" coax at baka maging brite ang tunog. But, sabi nya subukan lang daw nya muna - besides, he can easily order 4" fullrange speakers with any specs naman daw.
Lets just keep our fingers crossed ;)
-
Good day mga sir. :) Gusto ko sana itry tong design na ito and i was on my way into ordering the speakers... tanong ko lang kung meron specific spec akong dapat hanapin so I can make this design work???
I narrowed down my choices into 3 speakers.... patulong naman po mamili kung ano yung sa tingin ninyong mas suitable. TIA. :)

medyo mahal nga sir yung 8" na full range nila... kinoconsider ko yung hi-vi na 3" 700+ lang ang landed cost I've read a lot of good reviews about it narin thing is pang sealed ata siya... pwede rin ba ito sa zigmahornet na enclosure or dapat yung speaker na nakadesign for ported boxes ang kunin ko?
Thanks!

Hindi ko masasagot yan kasi nun nalaman ko price nung 8"er nila, hindi na ako nagresearch muli. :D Preo IMHO for P700, there's no harm in trying. Masmaliit naman ang enclosure ng sealed so matipid subukan. ;) Then make another zigma enclosure. I don't think uubos ka naman ng isang buong plywood for the sealed and Zigma enclosure.
Pwede mo din i-check ang mga drivers ng SEAS bro after ng experiments mo. Na-try ko na ang Lotus Reference nila sa oto. Pasado sa akin. Pricey nga lang pero sulit naman.
-
^ Okay yan - Seas or maybe even scanspeak ;) Yun nga lang medyo mahal sila.
May binangit sa akin si Atnhony dati na Sony speaker na talagang maganda raw sa vocals/mid. Galing daw ata sa mga Sony XBR TVs kaso talagang ubusan na at wala na stocks ::)
How big a departure kaya if instead of 4", we use a 5"? Of course a little bit of woodworks is added in the speaker mounting of the driver to implement the bigger driver.

Tapos 6", gaya ni Gino. Then 8" na. Wala na... Balik malaking drivers. Hehe! palibahasa malaki na house mo. ;) Buti na lang wala akong pera nung nakita ko yun excel 8" full range and tweeters.
-
@kemozavi - i think your short list of drivers will work too pero mabibitin ka sa bass. You will need a sub for the low freqs or lengthen the horn/pipe. I did a pair with a 9ft pipe with good results. Post ko rin ito once done. Parang parts express ang souce mo sa mga drivers. If I may suggest, try checking out the pioneer 4" fullrange. If memory serves me right, 70hz ang fs niya. S15-20 lang yata isa.
Anyway, just finished the horn tweeters that will be mated to the Sony drivers in a horizontal Zigmahorn. Since the Magnavox horns are 16 ohms and very efficient,I added a -6db L-pad and a 0.47uf Sprague oil cap for a cutoff of around 16khz.
(http://i296.photobucket.com/albums/mm180/trod93/DSCN0884-1.jpg)
Magnavox horn tweeters in custom made mount. I placed wood on the lip of the horn to dampen it and minimize ringing. Medyo may harshness ang highs without it.
(http://i296.photobucket.com/albums/mm180/trod93/DSCN0886-1.jpg)
The rear cover of the horns are actually the cap or cover of a canned spray paint which I cut to 3/4" thick. The original rear cover of the horn tweeters are made of styro. Kinain pa ng ipis kaya pangit na tignan. Now they look neat.
(http://i296.photobucket.com/albums/mm180/trod93/DSCN0882.jpg)
Side view.
These horns will be placed on top of the horizontal Zigmahorn. I'm just waiting for the polyurethane varnish to dry up on the walnut veneers. I'll post the finished product tomorrow.

Galing lang ako kina Tony a while ago. You have to see the finish in person to fully appreciate. It really blended well with the zigma.

The owner got the modified zigma yesterday. If you could see his face once he saw it. Anyway, he said he will post his impressions very soon.

The former zigma was wrapped in vinyl laminate only. Now in real walnut veneer.
(http://i296.photobucket.com/albums/mm180/trod93/DSCN0936.jpg)
In the owner's lair driven by a Cayin EL34 pp tube amp. Very nice combo.
(http://i296.photobucket.com/albums/mm180/trod93/DSCN0929.jpg)
The 3rd variant of the Zigmahorn with a 9ft, 3-fold pipe, tested and ready for finishing.
Since maganda resulta ng tweeter,I will put a Neo 6 planar ribbon tweeter on the orig Zigmahornet floorstander. I still have a pair of Sony drivers, so, isang design pa uli.

Thanks ctjader, ojofool and romymartinez.
The Zigmahorn design is very easy to make and versatile. You can experiment with different pipe lengths and come up with the same, or, even, better results depending on your goal, as long as you maintain the internal dimensions of the pipe.
In looking for the right driver, try something that has very good excursion (xmax) to attain better bass. The basic principle of producing very good bass is for a driver to move a lot of air. I used a Fostex FE-108 sigma and bitin sa bass. You will need a sub for this driver. I've experimented on different designs na, ie, Nagaoka double-horn, voigt pipe, and I always get the same result.-poor bass.
@kemozavi- the best driver among the 3 is the Hivi B3n coz its fs is 77hz and xmax is 3mm. But, it doesn't mean it will yield very good bass, just better than the other 2 drivers.
As for the use of plywood, 1/2" marine plywood is still the best. Manipis tumunog ang 3/4". This has something to do with the resonance inside the chamber. I used 3/4" ply on my 3rd variant but only on the external cabinet para lumapad lang ang width. The internal chamber is still 1/2" ply and a longer pipe (9ft.) to compensate for the tightness of the low freqs. Among the 3 variants, IMO, this has the best all-around presentation.
Hope to see your Zigmahorns very soon.
Goodluck.
Tony

sir trod93,
sakto ito sa mga t-amp owners! ;D

Saktong sakto rene. Kaya nga nagka-interest ako sa Lepai ta-2020. Small footprint pareho, amp and speakers, minimalist ang dating. Ang wife ko ayaw ng audio sa sala kasi nakakasira daw sa design niya. Well, if you have speakers that can pass as decor and an amp no bigger than a pocketbook plus an ipod, voila. Baka makalusot kay misis. Hehe.

I can relate with you bro. That is why I chose Zigmahornet and will only use same amp of Bose companion 2 ( powered speaker kasi ito). I will only tweak the amp for better sound reproduction. The Zigmahornet will be posted maybe early October. :)
-
Sana the Bose will be a good match. Can't wait to listen to your zigmahorn. Gusto ko kasi marinig other drivers on this design. Sony and fostex pa lang nasubukan ko.
Go for it bro. Once makita ng iba yan, dadami na gagawa nyan. Baka soon magka-Zigmahornet club na tayo. Hehe.

pansin ko yung sony driver na ginamit nyo ay similar or same sa ginamit ni Anthony sa 5 footer na nasa akin. mas mura ito kesa fostex but what about its performace/character sir?
what's so special about fostex nga pala? tnx ;)

Pag okay experiment kita kits tayo sa bagong bahay ni Vhongbiker sa Paranaque. At least itong Zigmahornet kasya sa loob ng kotse ko at magaan pa. If it will not work, I will have to order AN Super 3 in Cast Frame from U.S. Kaso, matatagalan pa yon dahil sa budget (magagalit si Kumander ;D). Kaya sana mag match talga Bose Companion 2 driver para masaya na ako at may magamit sa living room na pwedeng galaw galawin ng malikot kong bunso (2 year old boy). Kaya iyong set up ko AN at Sakura nasa kuwarto sa taas at bawal ang batang malikot >:(.
Until then bro. ;)

OT: hehehe ... type na type nga pala ng bunso mo iyung audio set-up mo ...

Actually, I don't know the parameters of the Sony driver. It has lush mids and what makes it ideal for this design is because of its excursion. Makikita mo talagang bumabayo. So, that takes care of the bass. Bitin ng konti sa highs unless you want a little laid back sound. A tweeter, tuned to the right cutoff, can give you that additional extension. According to Anthony, the Sony driver's top end is only 17khz.
I had 6 pairs of Sony drivers kaya napilitan ako gumawa ng modifications from the original design. Maduduling ka na kapag parepareho na lang nakikita mo, hehe. I'm now down to 2 pairs. 1 pair left for another experiment. Plano kong gamitin as mids in a 3-way design. Woofers na lang kulang ko.
With regards to Fostex naman, I would stick to its 6-8" drivers. I have a pair of FE-108 sigmas (4") at nahilo na ako kakagawa ng baffles. Can't find the right one until now. Maganda mids and top end, though, it needs a little more damping, medyo bright kasi. Need a sub for this driver. My post sa "pampagana sa mga diyers" was an FE-206e, an 8 incher. I had very good results with the blh.

Hopefully I can test tomorrow night the zigmahorny. ;D If successful, you tube video will follow on weekdays. :)

Ayos! Looking forward to seeing your work.

Bro, pasyal ako diyan next week.

The Bose Companion 2 amp with I.C TDA 7377 (use for car amp) was modified using rascal 101 circuit for better stereo imaging and details.
The sound quality is better on actual listening than what you see and heard (via quality headphone or computer speakers) on You Tube.
Thanks Mel for the ideas. Your creativity on the circuit you made will make all Filipinos proud. I am looking forward for your success someday. Para kang si Mang Rod.....isip ng isip para maka buo ng magandang tunog. Bihira ang mga taong katulad niyo. Simple circuit and design but big improvement on sound quality. Abnormal talaga kayo nila Mang Rod. You and Mang Rod's principles on audio are so radical. Principles that cannot be seen on books but only acquired by continuous experiment.
-
You're welcome Bro. You know it is when people believe in other people that an idea moves forward. Sana hindi ka magsasawa sa pakikinig sa mga iba't ibang ideya sa akin at mga kapwa natin :)
Thank you for letting me hear the Zigmahornet speakers and that delicious lunch :)

muntik ko ng di makita ang driver :) ayos na pala! congrats!
pero mas napansin ko ang pinto nyo ;)

how much was the landed cost sir for the cabinet, parts and labor? and is it through sir trod93?

Binarat ko nga eh. Anyway, experimental pa naman ito. Saka na pagandahin ng husto. Ako na lang titira ng finishing para makatipid. Simple lang gagawin ko. Thanks for your comments guys. :)

A Simple finish on the cabinet for a simple Zigmahornet speakers. For the meantime, I will use the Bose Companion 2 speaker driver on zigmahornet speakers. Since the experiment is successful, I am planning for Audio Nirvana Super 3 in Cast Frame which will cost me P5-7K approximately (including shipping and Phil.Custom :(). $78 lang pair pag sa U.S taga U.S lang. But of coarse not at this moment.
Here is the picture of finished Zigmahornet Cabinet.

Here is the Audio Nirvana Super 3 in Cast Frame $78 pair from commonsense audio of David Dicks, which I plan to use if budget really permits. I want to test it if it Super 3 is good as Super 8. Though, I am sure Super 8 has better frequency range.

Nice one monreq! Parinig naman. Those 2.8" Bose drivers look very cute on your zigmas.
@ninjababez
Actually, combination of 3/4, 5/8 at 1/2 plywood ito. Mga scrap plywood ko from previous projs. I'm experimenting on 2 configs right now: the Sonys mated with a neo3 plannar ribbon tweeter and another mated with a pioneer pt-205 horn tweeter. So far, the neo3 tweeters sound very good but a bit diffused. Naka-toe out sila to get better imaging. Ang ganda ng timbre. Sarap ihataw with the wharfe passive 12" woofers in a bi-amp config with a cut-off at around 50hz. Rene/ojofool suggested that i reverse the polarity. I will try this today and find out. Si ojofool ang experto sa mga neo3 having used and experimented on these for years na.

Ganda ganda ng install nya sa drivers ano? Flushmounted sa likod kaya di kita yun pinag-screw. :)
Sabi ko syo try mo reverse polarity eh. ;D Naks naman. Pa-bi-amp bi-amp na lang ang neighbor ko. ;) You forgot to mention na dual woofers ka na. And, active configuration na ang woofers mo. ;D

hahaha ala-tsamba lang ako, basta kumalansing ok na. ;D nakapako na ako sa "neo" sound. anyway kung gusto ko makinig ng horns, malapit lang. at kung gusto ko naman ng typical hi-end sound ng s.f., malapit din
ipa-calibrate mo sa friendly neighbor - the man with the golden ears master nelson!
try mo yung newer version up to 28khz. ma-pm nga si bigbert2 para sa feedback ng new neos nya
btw, sakto sa t-amps ang mga speakers mo ;D ::)

OK lang pala yung retaso bro, wala ba syang effect sa output? or i just have to make sure na pantay sila sa kapares? :D

May effect din if you mix them up. For ex., 3/4 kapal nung isa, tapos 5/8 naman yung isa. Or, naghalo yung kapal ng plywood. Most likely diffused yung sound. Kahapon ko lang napansin na baligtad position ng speakers kaya pala diffused. Ok na ngayon. I'm just making some adjustments para makuha yung pinpoint imaging.
-
ayos sir trod93, pwede na isabong ang zhorns mo! ;D
pag di pa solb ang tuning, baka kailangan magma-refer dun sa nag-tono sa horns nung taga-7th/f. ::)
ako, ok na ang toning ni johnny midnite sa setup ;D

The original wood used for the ziggies are birch ply.. I was thinking to make this project but i hold back due to availability ng birch ply.. Acoustically birch ply is better than marine.. I tried asking the two bald guys sa US
they said use 1/2 marine ply.. But im still worried cos theres a saying "the birch ply effect" which most speakers are using and never used marine ply.. It would really make a diffrence sa sound.. I also spoke with bro anthony before about the project he just said it would just fail bec of the wood that will be used i have to treat the marine ply internally to get the "birch ply effect" or else i need to make a baffle compensation circuit which should not be needed with the original zigmahornet plan

merrills were awesome :D
tb not yet, just installed it then display lang .. for now ;D
napakinggan ko lang saglit, at very low volume. kasi i finished installing the driver about 3am :D

Mkukang ganun na nga.. :) Bro try out class A amps.. Sa merrills ko ok naman.

Tried the single driver route before. These things are very revealing and coherent. Tubes appears to work better with this design. With paper based drivers and tubes - the voices are just right. More realistic than multi driver designs.
Great thing is source for these speakers are not that expensive - flea amps will do :)
After, the next real problem is getting good music files / recordings (I am shifting to digital files from CD). Reason I changed from this is that most pop recordings sound bad - and thats being kind. But I do listen to a lot of these kinds of recordings... >:(
Really nice DIY speakers here.

I understand what your trying to say..there are some recordings sound bad sa FR drivers so thats the same reason why I keep more than one kind of set up.. Depends on my listening mood.. :)

@bro Monreq ,
natuloy po ba yung plan nyo na kabitan ng AN yung Zigmahornet cabinet nyo?
how was it? how much po ba landed cost (Ph tax and shipping) ng 4" na AN kung sakali?
baka kayanin ng powers ng ipon to heheheh
